Hi Adam, I figured it out. To fix the issues of the project not importing. Do the following.
Click in Project Window
File>Import
Select the project file. It will then ask to import entire project or individual sequences.
Select Individual sequences. and Choose the SEQ you want.
Premiere will then pull in all the elements and the Sequence into a folder. double click the sequence and it opens up.
Repeat this proces until all your sequences, and content are back the way it was….Until they fix this bug.
I hope this helps
